Yesterday ZX-81 made available PSP7800 v1.1.2. This version is said to be the final release; yeah, like we haven’t heard that one before. You and I both know ZX-81’s track record.

PSP7800 is ported from Greg Stanton’s ProSystem emulator — it emulates the Atari 7800 console.

PSP7800 v1.1.2 changes:

• Major speed improvements (> 60 fps at 222Mhz) but limited at 50fps by default
• Auto-fire mode, press RTrigger+X to switch it on/off useful for games such as space Xevious!
• On given games, the auto fire can’t be stopped easily (so you might have to disable it several times)
• It uses now only PSP GU for rendering
• IR keyboard support (pretty useless, but don’t forget, I’m a shadok)
• Add several new hotkeys:
  • settings such as fps, render mode, auto fire speed can now be directly modified inside the emulator (no need to enter in the settings menu)
  • quick save / quick load current state (no need to enter in the main menu)
• RTrigger/LTrigger keys can be used in the keyboard settings menu to navigate between Normal, LTrigger and RTrigger compose mapping.
• Analog pad can be used in the rom file requester
• Default Hotkeys can now be set in the keyboard mapping menu (useful to add hotkeys on existing/previous keyboard files)
• Bug fix in the low battery watchdog
